SQLDMO_LPCSTR DBName,
SQLDMO_LPCSTR DataFile,
LPBOOL pRetVal) PURE;
Remarks
The AttachDBWithSingleFile2 method is used when a change to the location of operating system (OS) files implementing the database must be made visible to the SQL Server instance.
The DataFile argument specifies a single OS data file that implements storage for a SQL Server database. The SQL Server instance creates an operating system file for transaction log record maintenance as part of the AttachDBWithSingleFile2 method processing.
The AttachDBWithSingleFile2 method returns TRUE if the attach database operation succeeds. Applications that require detailed information regarding the success or failure of the attach database operation can call the AttachDBWithSingleFile method, which returns a detailed string containing this information.
Important The AttachDBWithSingleFile2 method only succeeds when storage for a database is implemented within a single operating system file. Files that implement storage for database transaction log records are not made visible by the method. For more information about making multiple databases visible to an instance of SQL Server, see AttachDB Method.
Making a database visible to an instance of SQL Server using the AttachDBWithSingleFile2 method requires appropriate permissions. The SQL Server login used for SQLServer object connection must be a member of the system-defined sysadmin role.
Note If an application calls AttachDBWithSingleFile2 on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000" are returned.
